Sustainable fashion for stylish women David's Bridal CT2406

I bought the dress from David's Bridal in Cincinnati, Ohio in December of 2012. My mother picked up the dress when it came in so the dress has never been worn. It has remained in the garment bag that we purchased especially for the dress. I am no longer getting married which is why I am wanting to sell the dress. I did also purchase a black satin ribbon (Style 3550) to go with the dress that has also never been opened.
